ACTIVATED CARBON SPHERES: PREPARATION USING TEDA CATALYZED PHENOLIC RESIN BEADS

摘要

Disclosed is a process for producing Activated Carbon Spheres, the process comprising the steps of a) preparing triethylene diamine (TEDA) catalyzed phenol-formaldehyde resin beads by polymerizing phenol with formaldehyde in presence of TEDA; b) carbonizing the TEDA catalyzed phenol-formaldehyde resin beads of step a) by heating in an inert atmosphere; c) activating the carbonized TEDA catalyzed phenol-formaldehyde resin beads of step b) by heating in presence of steam or carbon dioxide to obtain Activated Carbon Spheres.[IN-DEL-2013-01050A]
